Completed in 1900, 11 Union Square rises 12 stories over New York. Public records put it at 39 units and 89,289 square feet of floor area, on land zoned C6-4. It is carried on the public rolls at a market value of $6.9M, and assessed for tax at $3.1M. In the 35 years its record reaches back, the lot has drawn 1,475 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 579 of its 1,475 records, fully 39%, fall under that one heading. Enforcement (214) and release (190) trail well behind. No violations stand open against it today.

The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2011.

On the environmental ledger, the building posts an Energy Star score of 25, with a site energy-use intensity of 99.7 kBtu per square foot. Its operations answer for roughly 1,007 metric tons of CO2-equivalent a year.

Read together — 39% permit, 35 years of accumulation, a parcel of New York — these scattered records compose a portrait of the address that no single page sets out to draw.

$6.9M of New York, written across 1,475 government filings.
